I think most kids would fall in love when they saw this awesome Pirate Ship Playhouse. My kid did. 🙂

This 23′ tall Pirate Ship Playhouse is sitting on a real hollowed-out tree trunk.
To get inside, there is a ladder inside the trunk leading to a trap door, a the net on one side and a staircase on the other. This 12,000 lb Playhouse is 26′ in length.

Hammacher Schlemmer has more detail, including how much you’ll have to pay to have one in your backyard. I certainly can’t afford this one, but it inspires us (my husband 😉 ) to maybe try to figure out how to make it ourselves.
